非平衡プラズマによる微粒子生成 Aerosol Generation by the Nonthermal Plasma
This paper summarizes the aerosolization of hazardous air pollutants using three different types of nonthermal plasma reactors such as packed-bed, pulsed corona and capillary tube plasma reactors. The aerosol generation was initiated by the radical and ionic reactions between background gases and pollutants under plasma environment. Most of the aerosols produced under plasma were of a particle size much less than 100 nm (majority were 10 nm or less) through the cluster formation. Also, the core particles generated from the electrode materials by spattering may coagulate with clusters to form aerosols. The particle generation for CFC-113 increased with applied voltage (plasma power), but it was not affected by humidification. Aerosol generation of 1,000 ppm CFC-113 in air using the packed-bed reactor was approximately 10 particles/cm<SUP>3</SUP> at 8 kV for the particle size greater than 10 nm. The particle generation for 600 ppm toluene using the pulsed corona achieved over 35 particles/cm<SUP>3</SUP> for the particle size of 0.3 ∼ 0.5 μm and expected to be significantly higher than CFC-113 for the particle size greater than 10 nm.
